Make you breath
Two muscles found in the thoracic wall of both cats and humans are the external intercostal muscles, which help with inhalation by expanding the ribcage, and the internal intercostal muscles, which aid exhalation by compressing the ribcage.
The external intercostal muscles raise the ribs during inhalation, while the internal intercostal muscles lower the ribs during exhalation in a fetal pig.
The intercostal muscles are located between the ribs. They play important roles in breathing. There are two sets of intercostal muscles, external and internal. The external intercostals contract during normal inspiration, causing the rib cage to expand out and up and thus increase the volume of the chest cavity. The internal intercostals are used during forced expiration only. When they contract, the rib cage pulled down and together, shrinking the volume of the chest cavity.
The diaphragm and the intercostals are muscles that help breathing. When you excerise they work harder because it is harder to breathe.
The external shell of electrons is completely filled.
Yes.
external and internal intercostals
external/ internal intercostals
external intercostals and the diaphragm
External intercostal muscles are the ones between the ribs that help elevate them during inspiration.
Muscles of inspiration include: diaphragm, scalenes, pectoralis minor, and external intercostals. The muscles of expiration include: abdominals and internal intercostals.
I believe it is the External Intercostals that are responsible for protraction of the ribs.
the sternoclediomastoid, scalenes and external intercostals all work to increase throracic volume. hope that helps
The diaphragm is the prime mover of inspiration. It flattens on contraction, increasing the vertical dimensions of the thorax, which draws air into the lungs. The external intercostals also contribute to inspiration. The internal intercostals and rectus abdominis are expiratory muscles.
External intercostals
Im not expert, but isn't it the diaphragm and rib muscles, the muscles between the ribs, internal and external intercostals.
The Intercostals stabilize the rib cage and assist in respiration
